Need More Space Without Leaving the Home You Love?
A growing family, changing lifestyle, or lack of usable space can make a home feel smaller than it once did.
Too often, homeowners are stuck with:
-
Bedrooms that feel too small
-
Not enough space for family or guests
-
Cramped kitchens and living areas
-
No dedicated home office
-
Limited storage
-
Awkward layouts that no longer work
-
The stress and expense of moving
You may not need a new home. You may just need more from the one you already have.

WORDS FROM OUR RAVING FANS
Mark W.
“I've known the Carey Bros. Design & Build Remodeling for over 3 years now, and together we have been through 3 large projects. James and Morris treat their work as though they were working on their own home. It’s extremely difficult to find a company that can produce high-quality workmanship consistently.”
Ken K.
The Carey Bros are the complete package. They do what they say they’re going to do. Safe. clean, and on time. They are above and beyond my expectations and I'm picky.
Edmund G.
“Their detailed thoroughness and preparation, the performance and attitude of their onsite crew, post-job clean-up and follow-through demonstrate not just professionalism and experience but love, a sincere care and passion for what they do.”
Phil C.
The quality of our lives has changes because of this home that we are able to enjoy. I think what stands out with Carey Bros. is that they really demonstrate their passion. It’s not just a job to them. Everyone was very focused. A lot of passion went into the project and a lot of pride.
John J.
We first hired the Carey Bros. Design & Build Remodeling in 1995 to remodel our 42 year old kitchen. Morris' wife Carol designed the new kitchen counter and cabinets. James and Morris then proceeded with the renovation in a professional manner, including cleaning up after each day's work. In May 2014, severe cracks occurred overnight in our living room ceiling and exterior stucco walls, apparently caused by drought-related earth movement. We called upon the Carey Bros. Design & Build Remodeling who did a thorough investigation, and who proceeded to correct the problem by installing screw jacks where needed underneath the house to level the floors. Here again the work was completed in a professional manner. We are highly pleased with their work.
Lillian B.
I've been enjoying my new Carey Bros Kitchen for the last year. It is a pleasure to walk into the light, bright space every day, The beauty of the cherry cabinets and the granite countertops are outstanding. The extra storage space in the drawer banks and pull out cabinets make a huge difference. The under cabinet lighting makes preparation and clean up a breeze. I highly recommend the Carey Bros remodeling team.
Tom R.
James and Morris were both great. They did everything efficiently and preplanned. There were no problems.
Neil L.
Awesome work, very professional. Matched everything perfectly, they went above and beyond my expectations.
Karen F.
My husband and I contacted Carey Bros. Design & Build Remodeling for our kitchen remodeling project. I have to say that everything from design to finished project was absolutely perfect. We worked with James for design and then Carol helped with design as far as products such as granite and tile backsplash and paint colors. Their communication was the best I've ever had from any contractor. Field Superintendent Matt was great to work with. Every night we received an email letting us know what was going on the next day and who would be at our house. All of the workers were very polite and courteous and kept a very clean workspace. This was the best contracting job we've ever had! Our project turned out beautiful and I would highly recommend Carey Bros. Design & Build Remodeling for any of your contracting jobs! You won't be disappointed!
Angie C.
It is our forever home. We didn’t think that we would have gotten the house without the remodel and it really has exceeded our expectations in every way possible. We spend every single day in the kitchen. Almost 70% of our time in the house is around that island, so it really has been a big part of our life and probably forever.

How much does a home addition cost?
The cost depends on the size and type of addition, structural requirements, finishes, plumbing and electrical needs, site conditions, and the overall scope of work. We’ll discuss your goals and help you understand the expected investment during the planning process.
How long does a home addition take?
Timelines vary based on the project’s size and complexity, permitting, material availability, inspections, and construction requirements. We’ll provide a project schedule so you know what to expect.
Can you make the addition match my existing home?
Yes. We carefully consider architectural details, materials, finishes, rooflines, flooring, trim, and other elements so the addition feels connected to the original home.
Can you add a bedroom to my house?
Yes. Additional bedrooms are a common reason homeowners expand their homes. We can help evaluate the available space and develop a plan that fits your home and goals.
Can you expand my kitchen or living room?
Yes. An addition can enlarge existing spaces, including kitchens, dining rooms, family rooms, and other shared living areas.
Do you build primary suite additions?
Yes. We can create new primary suites that may include a bedroom, bathroom, closets, storage, and other features tailored to your needs.
Can you add a second story?
Depending on the home, lot, local requirements, and structural conditions, a second-story addition may be possible. The first step is evaluating your property and project goals.
Will I need permits for a home addition?
Home additions generally require permits and may involve planning, structural, and building approvals. Our team can help guide the project through the required process.
Can I stay in my home during construction?
In many cases, yes. It depends on the size and location of the addition and how much the work affects your existing living areas. We’ll discuss what to expect before construction begins.
Do you handle design and construction?
Yes. Carey Bros. Design & Build Remodeling provides an integrated design-build approach, helping coordinate the project from early planning through construction.
How do I know whether an addition or a remodel is better?
It depends on your goals. Sometimes an existing layout can be reconfigured to create the space you need. In other situations, additional square footage is the better solution. We can help you evaluate the options.
Will a home addition increase my property value?
A well-designed addition can add usable square footage and improve the function and appeal of a home. Actual value depends on the project, location, market conditions, and quality of the work.
Do you subcontract?
Carey Bros. manages the remodeling process and coordinates the skilled professionals needed to complete each phase of the project properly.
Will someone keep me updated during construction?
Yes. Clear communication is an important part of our process. We keep homeowners informed about progress, schedules, upcoming work, and important decisions throughout the project.
Do you offer a warranty on your work?
We stand behind our workmanship and will explain applicable warranty coverage as part of your remodeling agreement.
